Certifications and Standards

When it comes to lithium battery cells, there are certain certifications and standards that must be met in order to ensure safety and quality. Some of the most important certification bodies for lithium batteries include UL, CE, IEC, and UN38.3.

UL is a world-renowned safety certification body that tests and certifies products for safety. CE is a European Union certification that shows compliance with health, safety, and environmental protection standards. IEC is an international standards organization that develops standards for all kinds of electrical products, including lithium batteries. UN38.3 is a United Nations transportation standard that covers the shipment of lithium batteries by air.

In order to meet these various certifications and standards, lithium battery cells must go through rigorous testing to ensure they are safe and reliable. This testing includes things like thermal stability testing, overcharge/discharge testing, vibration testing, shock testing, and more. By meeting all of these standards, you can be sure that your lithium battery cell is safe to use and will perform as expected.

IV curve

Lithium battery cells have a very flat IV curve, meaning that the voltage stays relatively constant as the cell is discharged. This makes them ideal for applications where a consistent voltage is required, such as in smartphones and laptops. The main downside of lithium battery cells is their high cost, which is due to the expensive materials required to make them.

Electrical performance

Lithium battery cells have a number of advantages over other types of batteries in terms of electrical performance. They have a high energy density, which means that they can store more energy per unit volume than other types of batteries. They also have a high power density, which means that they can deliver more power per unit volume than other types of batteries. Finally, lithium battery cells have a low self-discharge rate, which means that they will retain their charge for longer periods of time than other types of batteries.

Electrical performance parameters

Lithium battery cells have many performance parameters that dictate how the cell will behave electrically. The most important of these are the open circuit voltage (OCV), the nominal voltage, the cutoff voltage, and the discharge efficiency.

The OCV is a measure of the potential difference between the electrodes of a lithium battery cell when no current is flowing. It is typically around 3.6 volts for a Li-ion cell. The nominal voltage is the average voltage that the cell can produce during discharge. It is typically around 3.7 volts for a Li-ion cell. The cutoff voltage is the minimum voltage that the cell can be discharged to before damage begins to occur. It is typically around 2.5 volts for a Li-ion cell. The discharge efficiency is a measure of how much energy from the cell actually gets used by the load, versus being lost as heat or other forms of waste. A good discharge efficiency is around 80%.

Nominal test conditions for IV parameters are standard test conditions (irradiance 10.0 Wm7, AM 15, cell temperature 25'°C) all measurements are guaranteed at laminate leads.NOCT measures wind speed at 800 W/m², 20C ambient temperature and 1 m/s.Specifications are subject to change without notice.
